Letters Patent No. 63,582, dated April 2, 1867 antedated March 20, 1867.

IMPROVED BURGLAR ALARM.

TO WHOM IT MAY CONCERN:

Be it known that I, JACOB Gr. TROUT, of the city of Philadelphia, and State of Pennsylvania, have invented a new and improved Burglar Alarm; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings and letters of reference marked thereon. In the accompanying drawings Figure 1 represents the back of the body F, and fig,4 the front of the same. The screw e in fig. 1 represents the fastenings to the door or window frames, which are cast into the back F-. jjjj, in fig. 1, represent six ears through which screws or rivets are placed to combine the back of body F to front of body F in figs. 1 and 4.

Figure 2 represents a view of front of body F, showing nipple A, which receives a percussion cap, the explosion of which causes thealarm. 0 represents the posterior view of the aperture through which the percussion cap is placed on the nipple A; it represent two grooves in which the hammer or steel rod B, in fig. 3, works; lZis the right-angled groove in which the handle I), fig. 3, works, for cocking and exploding 'the pereussion cap. 0, in

Figure 3 represents a steel coil spring which forces the hammer or steel rod B into the percussion cap, when the handle 6 is pushed out of the lower right-angled groove Z. The coil spring O rests on bottom a, of front of body F, in fig. 2, and against shoulder is of handle 6 in fig. 3.

Figure 4 represents a view of the front body F, containing nipple A; aperture 0, steel rod or hammer B, and handle 6, turned into lower right-angled groove Z, which shows the alarmist cocked, ready to fire off the percussion cap.

Figure 5 represents a complete view of the burglar alarm when the hammer B rests against the nipple A.

To give a full description of the construction, use, and operation of the burglars alarm, I would state that the body, back, and front F F, in figs. 1, 2, 4, and 5, are cast separate the screw e, in fig. 1, is cast into the back, and this back and front of body are connected by screws or rivets. The nipple A, in figs. 2, 4, and 5, is cast of malleable iron or steel, and riveted in the top of the body. The spring C, fig. 3, is made by machinery, and inserted over rod B, and set in body resting on bottom 7', in fig. 2, and shoulder K,*fig. 3, of handle Z2. The rod and handle may be cast of malleable iron in one solid piece, or separate, with brass handle and steel rod. The opening 0 in figs. 2 and 4 is necessary to place the percussion cap on nipple A.

Constructed in this manner the apparatus can be made cheap, is durable and harmless, and in case one piece of the compound parts is injured or lost, another will take its place. The modes of its application to doors, windows, and 860-, are as follows: First, to doors that open into the apartment from which you wish thieves or intruders to abstain from entering, you fasten the burglar alarm to the frame of the door by screwing into the wood the screw 2, in fig. 1, so when it is cocked the handle 6, in fig. 4, rests closely against the inside of the door, audit the door is opened as much as one and a half inch, the alarm made by explosion of percussion cap is complete. If it be a window you wish to secure, you screw the alarm in an opposite direction. to the movement of window, and fasten a stringer cord to window or handle 6, fig. 4c, and if the window is opened, oii' goes the alarm.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of body, back, and front F F, nippleA, rod or hammer and handle 13 6, spring 0, rightangled groove Z l, screw 6, and all as described and for thcpurpose set forth.
